@mia That thread doesn't have any information about the subject of this thread. Actually, after reading through that thread in its entirety, I would say it doesn't have any information at all (lots of debate about chips and pins, though!). This post was intended to give people specific, useful information.
@Blue Skye I made a bunch of $10 donations to different charities, since I support the charities anyway it doesn't make any difference to me whether I get 1x or 3x, but I'll update when my statement closes to identify which of them charged through as charity for the purposes of FlexPerks.
@HansGolden The Plastic Jungle deal is definitely not worth it most of the time, but like I say, there are situations where people could use it to bump up to the next FlexPoints tier, since the Skymiles->FlexPoints turnaround is only about a week.
